Yes CAT5E will work very well, gigabit up to 100m length with very low latency.Is good to play online games like csgo and upload videos a bit faster? (Also, It will work fine with a Asus n600 router?) (Btw, I am using a mexincan network called telmex)
I try it this aftermoon and it went great, I played a match with no lag, thanks broGood quality Cat5e cable gives gigabit performance, out to 100 meters.
It is unlikely that your PC/laptop/router has ports that are capable of more than that.
It is also unlikely that your actual internet connection speed is close to that.
Yes, good quality Cat5e cable is just fine.
